Part 1. Preliminary Reasons For Cellular Network Not Available For Voice Calls

Facing the “Cellular Network Not Available for Voice Calls Android“ error can be overwhelming. Thus, it becomes evident that specific reasons underlie this issue. Solutions indeed exist to tackle this problem. Yet, comprehending the underlying reasons is equally crucial to resolve the issue:

1. Internet Access

One primary reason behind cellular network unavailability glitches lies in unstable internet access. Voice calls over cellular networks often require a stable internet connection. When this connection fluctuates or drops, it can result in the dreaded error message.

2. Terrain Coverage

Another contributing factor is the geographical terrain. In remote or sparsely populated areas, cellular tower coverage might be limited. It causes a signal disturbance or complete loss of the network.

3. Network Congestion

During peak usage hours or in densely populated areas, network congestion can also be a cause. It leads to temporary unavailability of the cellular network for voice calls. When the network is overloaded with traffic, it might struggle to accommodate more voice calls. That results in connectivity issues.

Part 3. Check Wi-Fi Router settings

The third step you’ll want to take is making sure the internet router in your house is working properly and is actually sending internet data to your Vivo Y78+. Of course, if you have other internet-enabled devices connected to the same router and they’re working fine, you know this isn’t the problem.

However, if you’ve got a problem with Wi-Fi not working on your Android and other devices in your home or office, you know you’ve got a router problem. Here’s how to solve it.

  1. Go to your internet router and check the indicator lights
  2. While this depends on your device, a green or blue light will mean the connection is good, whereas a red light indicates a problem
  3. Press the Restart button on your router and wait ten minutes before reconnecting your device and connecting again
  4. Call up your internet provider to see if there’s an internet connection issue in your area
  5. Open your web browser and log into your router settings to ensure your Vivo Y78+ is connected to the Wi-Fi network and is allowed to send and receive data

Part 4. Boot your Android in safe mode

![wifi not working on android - safe mode](https://images.wondershare.com/drfone/article/2019/04/android-safe-mode.jpg)

If you’re unable to connect to the internet, but other devices have no issues, you may find the issues is coming from within your Vivo Y78+ itself. Fortunately, there are ways you can see whether this is the problem.

The best way to do this is to boot your device in Safe Mode. The process for doing this will depend on the make and model of your Vivo Y78+, but the basic process goes as follows;

  1. Turn off your Vivo Y78+ by holding down the Power button and tapping Power Off. Wait a few minutes to ensure the Vivo Y78+ device is completely off
  2. Press and hold the Power button to turn your phone on, but the press and hold both the volume up and volume down buttons at the same time

If your device connects to the internet while in Safe Mode, you’ll know you have a problem with an app or service that’s running on your device. If this is the case, you’ll need to go through your apps and delete them and then reinstall them one at a time until you find the app or service that is causing your internet problems.

Part 5. Check the Android Wi-Fi adapter

If you’re using a Wi-Fi adapter on your device to connect to the internet, you’ll need to make sure this is working. This could be an adapter on your Vivo Y78+ itself, especially if you’re using an older device, or if you’re using an adapter to boost the ranger of your router network.

You need to check both of these to make sure your connection is working properly.

  1. If using an Android Wi-Fi adapter, make sure all the Vivo Y78+ device drivers are up to date, and if you’re using an app, make sure the app is updated, and all the settings allow an internet connection
  2. If you’re using a router adapter, make sure it’s set up properly, and your Vivo Y78+ is connected to the adapter using the correct passwords. Try connecting another device to see if the internet connection is working on there
  3. Whichever method you’re using, try disconnecting your Vivo Y78+ and forgetting the network, and then reconnecting and entering the right password to refresh the connection

Part 6. Check SSID and IP address on Android

To make a Wi-Fi connection work, your Vivo Y78+ needs to match two codes that connect and relate to your router to establish the connection and work correctly. These are known as the SSID and the IP address.

Every wireless device will have its own codes and making sure they’re matched to the network you’re connecting to is crucial to ensuring the internet is working on your Vivo Y78+. Here’s how to check on your Vivo Y78+ to make sure everything is correct.

  1. Tap the Settings menu option, followed by Wi-Fi on your Vivo Y78+
  2. Turn on your Wi-Fi network and connect it to your router
  3. Find the router name (SSID) and make sure it’s exactly the same as the SSID written on your router
  4. Once connected, tap the Wi-Fi network and you will see the IP address. Check both your phone and the router codes to make sure this number matches

When these numbers are matching, if your Android is still not connecting to wifi, you’ll know this wasn’t the problem.

Part 7. Fix Android system issues in one click

If none of the solutions above are working, this could indicate a real problem with the firmware and operating system of your Vivo Y78+. Fortunately, a fast solution to get everything working again is to completely repair the software of your phone.

Part 9. Change the password of the Wi-Fi

Each Wi-Fi network router will give the opportunity to choose and change the password you have to let devices connect to your network. It’s important you try changing this because you never know if someone else has accessed your network and could be blocking your device. Here’s how it works;

  1. Log onto your computer and open your Wi-Fi settings
  2. Depending on the brand and method of your individual router, navigate to the Wi-Fi password settings menu
  3. Change the password to something complicated using all available digits and characters
  4. Save the password and restart the router to disconnect all devices
  5. Now connect your Vivo Y78+ to the router using the new password

Part 10. Reset network settings on Android

Just like the method above where you’ll be effectively resetting the network settings on your router, if this hasn’t worked, you’ll be able to reset the network settings on your Vivo Y78+, hopefully removing the bugs and allowing you to connect.

Here’s how you can do this easily on your Vivo Y78+;

  1. From the home screen of your Vivo Y78+, open the Settings menu
  2. Tap the Backup & Reset option
  3. Tap the Reset Network Settings option
  4. Tap the Reset Network option
  5. If you need to, enter the PIN number or passcode for the Android device, and the Vivo Y78+ device will confirm the reset has taken place
  6. Reconnect your Vivo Y78+ to your Wi-Fi network for the changes to take effect

Part 11. Clear partition cache in recovery mode

As you continue to use your Vivo Y78+, the partition cache will fill up with data your device needs and doesn’t need. However, by clearing your device’s partition cache, you can make clear up some space which should help your device have enough memory to connect to the internet.

  1. Turn off your Vivo Y78+
  2. Turn it on by holding down the power button, volume button, and home button
  3. When your phone vibrates, let go of the Power button, but continue to hold the volume button
  4. When a menu is displayed, use the volume buttons to navigate the menu
  5. Select the Android System Recovery option, followed by Wipe Cache Partition
  6. Restart your device and connect to the internet

If worse comes to worst, another option you have is to factory reset your Vivo Y78+. As we’ve spoken about above, while using your phone from the day you started using it, your device will fill up with files and data which can become messy and causes bugs.

However, by factory resetting your device, you can start again from the factory default from which you first received it, ultimately clearing the bugs. Make sure you back up your device before proceeding because it will erase your personal files.

  1. Open the Settings menu on your Vivo Y78+
  2. Navigate to System > Advanced > Reset Options
  3. Tap the Reset phone option, and enter your PIN code if required
  4. Tap Erase Everything
  5. Wait for your phone to complete the process
  6. Restart your device and connect to the internet
